Title: Zhen Jin: Innovator in Data Storage Technologies
Introduction
Zhen Jin is a prominent inventor based in Fremont, CA, known for his significant contributions to data storage technologies. With a total of 8 patents, he has made remarkable advancements in the field, particularly in the design and functionality of read transducers and write heads for hard disk drives.
Latest Patents
One of Zhen Jin's latest patents is focused on an angled free layer for multi-level read signals. This invention describes read transducers, data storage devices, and methods that provide an angled free layer for generating and decoding multi-level read signals. The read transducer features a free layer with a magnetization bias that is sensitive to external magnetic fields, forming an acute angle relative to the surface of the non-volatile storage medium. Additionally, the read transducer includes a pinned layer with a fixed magnetization, which is oriented at a right angle to the magnetization bias of the free layer. This innovative design targets a readback location on a track boundary between adjacent tracks, generating a read signal that reflects both perpendicular and cross-track fields of the adjacent tracks.
Another notable patent involves implementing asymmetric degauss control for write heads in hard disk drives. This method, apparatus, and system enhance the degauss control process by providing a degauss period at the end of a write operation. During this period, the write head is driven asymmetrically concerning the positive and negative driving currents, resulting in a non-zero average value of the write current.
